INK-WELL.

To all whom it may concern/.-

Be it known that I, JAMES W. JACOBUS, a citizen of the United States,residing at Great Neck, county of Nassau, State of New York, haveinvented certain new and useful Improvements in Inkells, of which thefol lowing is a full, clear, and exact description.

My invention relates to ink-wells, and particularly for school-desks.Such ink-wells are often subject to very careless and rough usage andmust satisfy a great many conditions some of which are antagonistic toeach other. They must be cheap, durable, easily installed, small inexternal dimensions, but of substantial capacity. They must preventevaporation, exclude dirt, dust, and other.

foreign particles, prevent application of an excess of ink to the pen,prevent children from sticking their fingers in the ink, and must beeasy to clean and fill. It is my object tofulfil these conditions.

The invention consists in the practical embodiment of the principleshereinafter set forth and illustrated in the accompanying single sheetof drawings.

Figure 1 is a plan view of a fragment of a desk with an ink-well of myinvention installed. Fig. 2 is a vertical sectional view of the same.Fig. 3 is a horizontal sectional view of the body of the ink-well, takenon the plane of the line as :13, Fig. 2. Fig. 4 is a detail sideelevation of the tube which forms a vertical extension of the mouth ofthe well.

The desk-top 1 is provided with a circular opening. having an annularshoulder 2 for supporting the ink-well. The nk-well body 3,semicylindrical in form, is preferably formed of a single integral wallof glass having a laterally-projecting flange 4 at the upper end,adapted to be supported by shoulder 2. At an opening or mouth 6 in itsupper Wall; The upper wall 7 of the body is preferably arched slightly.The ink-holding reservoir will thus be seen to have only a small openingat one side. The reservoir may be readily filled through this 0 eningwhen the Well is tipped on its side. en upright in its normal positionof use, the ink cannot rise above the lower edge of the mouth-opening 6,since the reservoir is otherwise absolutely air-tight. The depth of inkbeneath mouth 6 is just sufficient to properly supply an ordinary pen.

To protect the upper part of the well, I

the base is a lateral extension 5, with Patented April 16, 1907.

prefer to provide a top having a central disk portion 8, aslightly-raised guard-rim 9, a reinforcin depending flange 10, and aninturned ange 11, gripping the body-flange 4 and securing the toppermanently to the body. In the top is an opening or mouth preferablyhaving the depending flange 12, located directly above the mouth 6 ofthe well and through which the pen may be dipped.

Upward from mouth 6 extends tube 13, preferably made of hard rubber orother suitable non-corrodable composition. The upper end of this tube ispositioned by the top flange '12. This tube in the form shown has itslower end inserted in mouth 6, so as to prevent eva ioration orincursion of dirt at this point. t is removable, so that the well may bemore easily filled. The ink cannot rise into the tube abovethe mouth 6of the body. The internal diameter of the tube is preferably onlysufficiently large to admit an ordinary pen.

The arched cover 14 is pivoted at 15 to the top disk 8 and is providedwith an opening 16 adapted to re ister with tube 13 when the well is inuse. E1 the position shown, how ever, the cover is in the closedposition, and neither evaporation or entrance of dirt can take place.Its arch form renders it more easy of operation. The entire constructionwhen installed is preferably flush with the top of the desk.

In the ,form shown the tube is the only part likely to be lost orinjured, and its cost is very small. It will be apparent that the tubemight be a permanent part of the well; but this entails specialprovision for filling, and I reserve the right to file a separateapplication therefor.

What Iclaim is 1. An ink-well comprising, an integral body portion,semicylindrical in form, and having a laterally-projecting flangeadjacent the top and having a laterally-projectin integral extension atthebase provided wit an upwardly-opening mouth, said mouth being butslightly larger than necessary to admit an ordinary pen and saidextension beneath the lower edge of said mouth being only deep enough tosupply the pen with ink.

-well comprising an integral a size and elevated above the bottom adistance only sufficient to permit the dip of an ordinary pen.

3. An ink-well comprising an integral body permanently closed at the topand at the bottom and having only one opening at one side near thebottom and a removable tube extending upwardly from said openingsubstantially to the line of the top of the body and of suflieientinternal diameter to permit dipping an ordinary pen to the bottom of thebody. i

4. An ink-well comprising a body having a laterally-projecting flangeadjacent the upper end, an integral laterally-projecting extension atthe base, an upwardly-projecting I tubular extension from saidlaterally-projecting extension and a protecting-top.

5. An ink-well colrprising, a body closed at the top and having a mouthat one side adjacent the base and a permanently-attached protecting-topprojecting laterally of said body.

6. An ink-well comprising, a body closed at the top and having a niouthat one side adjacent the bottom, a removable tubular extension mountedin said ITOUth and a pro teeting top member for said body and saidtubular extension.

7. An ink-well comprising, a body having a mouth at one side near thebase, a protecting-top having an opening over said mouth and a tubularmember extending upwardly from said mouth and removable through saidopening.

'8; An ink-well comprising, a body having a mouth near the bottom, aprotecting-top having an opening above said mouth, and a rotary coverhaving an opening adapted to ing an opening above said body-opening anda rotary cover having an opening adapted to register with said topopening.
